摘　　要：过滤器是保障微灌系统正常运行的核心设备,而水头损失与过滤效率是评价其性能的2个关键指标。为探明泵前过滤器—浮筒网式旋转过滤器的水力性能和过滤性能,采用方差分析、极差分析、主效应多重比较法对比分析了浮筒网式旋转过滤器在滤网孔径为0.150 mm时,5种不同含沙量、5种不同流量下的水头损失与过滤效率,并确定了试验条件下的最优工况。结果表明:对水头损失而言,流量比含沙量影响大;对过滤效率而言,含沙量的影响更大,且水头损失与过滤效率均随含沙量与流量的增大而增大;最优工况为流量930 L/h、含沙量2.0 g/L,此工况下对应的水头损失为0.281 m,过滤效率为84.01%,可以保证在有良好的过滤效率的同时具有较小的水头损失,从而实现节能减排,高效灌溉的目的。The filter is a crucial equipment for maintaining the proper operation of a micro irrigation system,and head loss and filtering efficiency are key indicators for evaluating its performance.To investigate the hydraulic performance and filtering performance of the pre-pump filter-float mesh rotary filter,this study employs variance analysis,range analysis,and main effect multiple comparison method to compare and analyze the head loss and filtering efficiency of the float mesh rotary filter under five different sediment concentrations and five different flow rates when the filter mesh aperture is 0.150 mm.The aim is to determine the optimal working condition under the experimental conditions.The results indicate that:flow rate has a greater impact on head loss than sediment concentration.Sediment concentration has a greater influence on filtering efficiency.Both head loss and filtering efficiency increase with an increase in sediment concentration and flow rate.Thus,it can be concluded that the optimal working condition is a flow rate of 930 L/h with a sediment concentration of 2.0 g/L.Under these conditions,the corresponding head loss is 0.281 m while achieving a filtering efficiency of 84.01%.This ensures good filtration effectiveness while minimizing energy consumption for efficient irrigation practices aimed at reducing emissions.
